Suitescript render pdf error with renderer.renderAsPdf()

Hi there,

We have a script will run to generate a PDF file when an Item Fulfilment update. The script has no problem for few years until today one user input an "&" character in a custom transaction body field.

I like to know is it's the limitation of renderer.renderAsPdf() function?

Error capture below:

{"type":"error.SuiteScriptError","name":"USER_ERROR","message":"Error Parsing XML: The reference to entity \"B\" must end with the ';' delimiter.","id":"","stack":["createError(N/error)","beforeSubmit(/SuiteBundles/Bundle 338648/UserEvents/srs_if_packing_invoice_ue.js:1160)"],"cause":{"type":"internal error","code":"USER_ERROR","details":"Error Parsing XML: The reference to entity \"B\" must end with the ';' delimiter.","userEvent":"beforesubmit","stackTrace":["createError(N/error)","beforeSubmit(/SuiteBundles/Bundle 338648/UserEvents/srs_if_packing_invoice_ue.js:1160)"],"notifyOff":false},"notifyOff":false,"userFacing":false}
